Man, next time bring the pizza, $100, and the parts
And you and I will fix it in my garage.
I did the entire system on my H3 (radiator, t-stat, water pump, HD fan, and fan clutch, hoses, serpentine belt , idler and tensioner pullys and special tools for around $600. Granted , I got some good deals on some of the parts, but still..
Same job on my 540i was roughly $400, but I didnt get a new fan though (i did do the clutch).
Itd be a shame to spend $1200 and only get the pump done. .
